' SPECIFICATION forming part of Letters Patent No. 761,611, dated May 31, 1904.

Application filed September 17,1903. Serial No. 173,637. (No model.)

T0 aZZ whom it may concern: I

Be it known that I, GHARLEs F. RITCIIEL, a citizen of the United States of America, and a resident of Bridgeport, county of Fairfield, and State of Connecticut, have invented certain new and useful Improvements in Trolley- Poles, of which the following is a specification. i

My invention relates to the trolley-carrying poles used on electric cars for making connection with overhead conducting-wires to conduct the electric current into the cars; and the object is to provide simple and efiicient means for lateral vibration of the trolley-wheel relatively to the pole under the diverging movements of the pole relatively to the conducting-wire and at vthe same time support the axis of the trolley-wheel in such alinement with the trolley-pole that when in passing under bridges and other low structures the pole has to be forced down to a level position, or thereabout, the Contact of the trolley-wheel and conductor will not be interfered with, as Where the trolley-wheel is carried on a laterally-swinging upper section of the pole that is cranked or deflected out of alinement with the axis of the pole to enable the trolley-wheel to be so swung by the deflections of the pole relatively to the conducting-wire, as hereinafter described, reference being made to the accompanying drawings, in which- Figure l is a side elevation of a trolley-car having the pole contrived in accordance with my invention. Fig. 2 is a detail in plan view illustrative of the lateral action of the trolleywheel. Figs. 3, 4=,'and 5 are details showing modifications of the Connection of the vibrat ing part of the pole carrying the trolley- Wheel with the main part of said pole.

A represents the main part of the trolleypole. It is mounted in the usual manner on the top of the car, so as to swing vertically on the pivot Z) to cause the wheel 0 to run in contact with the conducting-wire d under varying relations of the height of the wireand the car. The pole is somewhat shorter than .as ordinarily arranged and at its upper end socket is in alinement with the main part of the pole and the extension part is bent downward to provide the oifset enabling the wheel .to vibrate, and yet the wheel is carried sufficiently high forgood contact with the wire even when the pole is forced down to the level plane, which is not the case when the socket is in alinement with the main part of the pole and the extension part is offset, as the extremity of the main part is then higher than the wheel when the pole'is forced down to any material extent and prevents contact of the wheel and the wire.

In Fig. 4 I. have represented the shank g of the extension part f of the pole as capable of shifting vertically in the socket 6, with a spring in to thrust it upward as an elastic structure to relieve the parts from shocks, and in Fig. 3 I show the extension part f -as con: sisting of a spring for the same purpose, the spring being held in the socket e by a pintle c', on which the spring may turn, or which may turn in the socket. for the Vibrations of the trolley-wheel.

The extension part of the pole may have unlimited lateral vibrations in the socket, or the same may be limited, if desired, which may be provided for in any approved way,,as

by a stud-pin j in the shank or pintle and a part, and means for elastic support of said ex- 1 groove is in the socket, as shown in Fig. 5; tension part on the main part of the pole. also miFlg. 1.
